Ok here what I have done so far. I have changed the fuel pump and fuel filter. Changed plug and wires. Fuel pressure regulator has also been changed. The only way I can get it actually run is spraying carb spray into the intake. I have checked for vacuum leaks but not that would keep it from running.

I was starting the engine and let of the ignition too soon, turned the key again and when the engine started it was at a rough idle and then smoke and some sparks were seen under the dash somewhere or near the firewall. Now the idle is very rough and while it is drivable, I am 5 hours from home and need to leave on Wednesday morning. Any help would be appreciated very much.

brake pedal, when depressed, reaches the floorboard,,and will not stop readily, the brake fluid is full, and not appear to be leaking. what repairs will need to be done, and what will the expense be, estimate?

The vehicle was operating fine and traveling downhill on a freeway when the transmisson seems to have failed. The transmission has fluid but we have absolutely no power transmission in any forward or reverse gear. Before we replace the transmission can we determine that the transmission is the problem or is it a torque converter problem? If we decide that the transmission needs to be replaced are there any words of wisdom that may help us along the way?

I Have a 1988 Ford Aerostar, and the driver side front brake won't release. I've already replaced the caliper, but that hasn't fixed the problem. Is there some other part of the brake system that would control the release of the brake pad.
